j ment with `the;` auxiliary `or emergency' ValveV I have found in practice that a resilient Valve seat of the character described7 is effective in operation, andthe valve member readily forms a liquid-tight joint therewith, particularly when there is a loose connection between thea valvemember:and:` thelvalve operating stem:` as` illustrated Furthermore, a resilient Valve seat of the trated requires no grinding to make a tight joint; andis vnotsubjecte'df''fto corrosion as" is the case Wit-lra metal Valveseat. `Titien-the valve seat is Worn out, it is readily replaced by removing the cage and inserting a new The emergency; Valve seat one in position. i is particularly Valuable When the resilient valve; seatbecomee, toof badly Wornfs tov malte a tiglfrtzjoint :at `t i imes Whenfit is ineonvenient on perhapsimpossibletzo; renewv the resilient yalywseat.
